INPOP new release: INPOP19a

We present here the new planetary ephemeris INPOP19a for the orbits of the 8 planets of the solar system, the moon, Pluto as well as 14000 asteroids. It is fitted over about 155000 planetary observations including 9 positions of Jupiter deduced from the Juno mission,

an extension of the Cassini data sample from 2014 to 2017 for the Saturn orbit and of the MEX data from 2016.4 to 2017.4 for the Mars orbit. The asteroid orbits were fitted on the almost 2 millions of observations obtained by the GAIA mission and delivered with the DR2.

Finally a new bayesian procedure for the computation of the masses of 343 main-belt asteroids has been applied and leads to an important improvement in the accuracy of the Mars orbit and of its extrapolation capabilities. INPOP19a is available on www.imcce.fr/inpop.
